IMPRO'VBMBNT IN MAomNBsron MAKING CHAINS.-

,TO ALL WHOM IT MAY CONCERNi:

Be it known that I, JOsIAII CorLEl", Jr., ot' Allegheny Cityyinthe county of Allegheny,'nnd` Stute of Pennsylvania, have invented a new and usef`u1""11n}oenent inV Chain Machines; und Il:fleherebydechire the -following to he al full and exact description thereof, reference heinghnd'to the'ucconipnnying drawings; and the letters and lignresof reference marked thereon. .l v i My invention consists in vso constructing a machine for forming-links for chains that it will grasp the iron when supplied -to it, form the link, cut the scarf, und give the desired overlap for welding,and continue to feed up the iron until it Yis entirely expended in forming links, said machine'bcing constructed', arrnnged, and operating substantially in the manner Ilwrcinnfter descrilied..

To enablcnothers skilled in 'the'urt to molke und use my invention, I will proceed to describe its .construc tion and operation. In the accompanying drawings, which form part of my spcciiitmtion;`

Figure l1 represents piecerfnsed for moving the springclnmp back ou `the iron, for. the purposeof cbt-nin ing the desiredcverlp f or welding. p p v l l p Figure 12represents a side view of the spring-,latch used for holding the wheel D in the desired position.

Fignrel represents o foce view of seid spring-latch. I 1 In. the drawings, A represents the frame of `the`macl1ine, whichmay be made of iron or.wood, andmay be secured down on any suitable beso. B represents the main shaft, which `is provided with a driving-wheel, D, 'and disk C. '.lhe driving-wheel D isprovided with cogs on only part of its periphery, said cogs heilig snieient in number to turn the wheel D one full revolution. portion of the cogs of wheel D -is' provided with shrouds Cf, which are used in connection with a piece,l J', on -the wheel D', for bringing into 4proper gear the `wheelsll) und D ,end also for the purpose of 'preventing the eogs from'knocking und jamming against each otherwhile coming into gear. The piece marked J is put in place of one'of/the cogs of the wheel`D, and extends out beyond the ends of the cogs nearly to the thickness of theshrouds C( on the wheel D. i'

The disk C'on the shaft B is rovidedw'ith a lifter, e, for operatinrf the cutter-lever A', a. in, o, for o er P u P P ntin lthe sv ri'nff Bl, and a ro'eetion, n, for im artn the desired motions to the clutch-leveren. The cutter- P e P J P ,g

lever As secured on shaft R, und is provided with -a lifting-point, f, and un urng, 'foroperating the support l y forthe mandrel c upon which the link is formed. The support y moves on un inclined wey, marked 5, .and

i's perted by the arm g, through the mediuurof the rod 4, which is pivoted and htteched to the "support y at the pointrnarkcd l, and is provided with collars 14 und 15 and a spiral spring, 8. The cntterdiolder or stock` lo moves in guides t', and is provided with two trunnions V, which work in suitable slots mede in the-end of the cuttcrlholder A'. The cutter tis secured in its holder h by means ef a set-screw or other .devce, nudr'nny he ndjustedso that it' will out the scarf of the linkI :tt nny desired angle. A

Thef'mendrcl e, around which the link is formed, may be part of the-shaft R', or it may he made in n sep. :irate piece, und secured to the shaftby any suitable means. The upper side of the mandrel 'c iat-provided with a. rib, marked e, the front end of which is furnished with teeth.A `In the upper side of themandx'el is maden n. recess, into lwhich is 4inserted n steel plete, x,4th'c front end of which must in form correspond to theun'gle of the cutting V.edge ofthe cutter t'. The form of and manner of securing the steel` plate :c1 in -themandrel are clearly shown in figs. 7 and 8. On the under side of the mandrel c is a rib orbrnce, flJlwliicli-isy `used forth. purpose of supporting end giving strength to the mandrel. y i

On the mandrel is placed n. collar marked a, whchs provided with a`hclical-fornied" edd', o recess, al", lend a groove marked b, in which the clutch 8 of the lever'm works. The recess 2: is usedV for receiving the end of p the rod from which the links are formed; und the key S, in connection with the lip z* of. the coller,` isnsed for grasping the end ot' the rod, which grasping of the rod, und the releasing of it'fro n1 the grasp oitho key and Vlip z of the coller, is effected by'moving the coller longitudinally on the mandrel, through the medium of the.

eluteh-lever i and the projection'n on the vdisk C. l The rod 1e passes throughI openin', e,"sl in the spring B? and B, and is adjustedand `secured to the 4spring B bymeans of screw-nuts 9. One end of the rod w is provided with afhead or collar, u, which is used for the purpose ot" drawing forward the spring B2, to' which' in attached the spring-clamp J, which is provided with-jaws P', the inner faces of which are' groovcd out, so` that they will `grasp around the rod from which the links are formed, and'hold it suiciently firm to cause it to wrap closely around the mnndrclin the process of formingthe link.

welding. A f v The fo1-u1,'size, and arrangemeutof the several parts'herein described may' be' varied, und the same general On the upper end of the springB, just abovethe spring-clamp J, is secured a Ut'shaped feed-guide marked ar. To the stock or cutter-holder k isattached andpivoted the piece marked 7c, )vhich'is madein the form represented in iig, 11. This piece lc straddlesthe fcedguide x, the partsmarked 2 restingA on. thespring-clamp, and so arranged'that they will press against that'pnrt-ofihe; springliz which is secured to thev sides 'of the U-shaped `feed-guide x, and is of such a length as will allow the spring-clamp Ito properly vfeed up the-iron of which the links areformed, and is set at such an angle, with relation to the'stoek h, that the downward motion Y of the stock 'will cause the piccola to press back against the spring'B2, and thereby-cause the feed-guide m and-` Springclampd' to slipbae'k on the rod which forms the link 'a suilicicut distance to give lthe desired overlap for result obtained; therefore I wish it clearly understood that I do not conlin myself to any one form, size, o1" arrangement of the parts, butleave this to the taste, skill,'and judgment of the mechanic. Ai the construction and arrangement of the parts, and the relation that these' parts .bear to each other will readily be under stood by the skillful mechanic from the description above given, and-by refercnc'i'to the accompanying drawing,

I will therefore, without furtherdescription,'proceed to describe the operation of my improvement in chain machines.V i

.-Wlien it` is necessary (which will always be the case in 'making heavy links) the iron is heated in suitable furnace. It is then placed in the fced-guide re, and in between the -jaws Psudiciently for the feed device to i bring it into the recess c." of the collar a; andvastho she-ft B, wheel D, and disk C revol've,-the pin o will come in contact with the springB, 'which draws-black the rod w, and the headu of tho rod w pressing against the springis, will 'carry forward the spring-clamp J and feed-guide 1f, which will thrust the' p'rojectiug'end of the iron into the r'ecss las of collar which is held out town-rd the. end of the mandrel c, by means of the clutch-lever m, acted upon bythe elevation n of the projection n on thedisk C. -The projection n having passed beyond the cud of thelcver m, the spring 10, pressing it 'toward the disk C, causesit'to move the collar a, so that lip :n, pressing the iron against the end of the rib s, 'holds it fast. Then the. shroud c en ivheel D, striking against bevel face ofthe latch Riz, pressesit backyreleasin'g the cross-pice J. on wheel D',

which 'is then set inlu-otion by shroud C acting on the cross-piece J', which motion is continued until it, together with the mandrel, has made one full revolution, wrapping the iron around the mandrel, the helical face of the'-V eollar a guiding it and giving it the desired form ofan openv link. The litter e on disk C, ,acting o'n the point v f of the cutter-lever A', causes thecutterstock z to descend, whiclrwill `'us'e the piece k to press backI the spring B?, togetherI withthe spring-clamp J, slipping`t11o jaws P of said clamp back on the irnnsuiiiciently to give the' desired overlap for the next link.- At the 'same time the support gis drawn up under the end of the mandrel by thc arm g pressing against the spring 3 on 'the connecting-rod 4. The 'motion of the support being checked by the web 16 of the frame A., theA spring 3yiclds to the further motion of the arm g. The

.descent of the cutter-stock 7L causes tl1e` cutter t, wbeli,'in connection with the steel plate n. in the mandrel,

V the purpose set forth.

nthcols D and D,as herein described,l and forthe'purpose set forth.

forms a paixof shears to cut oli` the iron, leaving the iron with a. scarf oorrespondingvwith the angle :it which' the cutter is set. The link beingr eut ol'f`,'the remaining yiron in the spring-clamp J will be carried back bythe action 'of the spring B2. At tho sometime cutter-lever A falls vbucleto its original position on the cross-piece P, `raising the cutter and its stock, and drawing buck thepieco c, and, by means of. the -arm g and rod 4, pushing bziek the support from bcneathtbe mandrel. The bevel face nl of the projdctionnon the disk C, pressing against incline 1,'I of lever m, moves the collar a outward, causing the collar to push the link off the mandrel. The end of lever then drops'down on the elevation n of the projection 1t, carrying the collar a back to the proper position for receiving the' iron into the recesses-'for the next link.
